Munro's globemallow attracts many species of bees, a few of
which are specialists, requiring pollen and nectar only from
Sphaeralcea and related genera. These include the ground-nesting
bees Diadasia diminuta, D. lutzi, and Colletes sphaeralcea. The
Diadasia are proficient and dedicated pollinators, and have been
found colonizing trial plots on research farms (Cane 2011).
